We're dividing 133961 by 43 
We're looking to find how many times 43 goes into 133961.

Going ahead to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 43

On to step 2:
The number 43 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 43

Moving on to step 3:
If we divide 133 by 43, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 129 away from 133, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 43

Going ahead to step 4:
43 goes into 49 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 43 from 49 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 43

Advancing to step 5:
66 divided by 43 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtracting 43 from 66 leaves us with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 43

Let's proceed to step 6:
43 can be fit into 231 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 3115.0
If we subtract 215 from 231, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 43, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 3115.3
Subtract 129 from 160 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
310 divided by 43 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3115.37
If we subtract 301 from 310, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
43 can be fit into 90 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3115.372
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3115.372
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 43 fits into 400 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 3115.37209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
130 divided by 43 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3115.372093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
43 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 3115.372093
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 3115.37209302
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 3115.37209302, and the remainder is 1.4e-08.
